Both sexes of this species have been minutely described by 

 Thorell. 



The South African Museum possesses only male specimens, viz., 



1 from Zandhoogte, near Eamonds Drift on the Orange Eiver 

 (Little Bushmanland), and 1 from near- Naroep (Great Bushman- 

 land), both places in Namaqualand Div. (spirit specimens, 3Iax 

 Schlechter) ; also, an old dried ^ specimen, labelled " Damaraland" 

 {F. Hodgson). The dried specimen measures 33 mm. in length, the 



2 spirit specimens 36^ mm. and 41 mm., while Thorell's ^ 

 measured 42 mm. and his ? 50 mm. Pocock's ? of cristatus 

 measured 62 mm. in length.

 the abdomen, excepting along the hind margins of the segments, 

 darkened in one specimen ; median eye-tubercle and a curved mark 

 on each side, enclosing the tubercle as in brackets, black. 



Cephalothorax somewhat wider than long or as wide as long, 

 finely granular throughout, the granulation coarser on the inter- 

 ocular area in the dry specimen ; median eyes unusually large and 

 near together, the distance between them only slightly exceeding 

 their diameter, the eye-tubercle finely granular. 



Tergites as in capensis. 



Sternites. — Segments 1-4 granular only at the extreme lateral 

 borders, segment 5 minutely granular throughout or smooth mesially. 



Tail moderate, sparsely hairy, the vesicle pilose. Segments 1-5
